SPECIFICATION forming 'part of Letters "Patent No. 244,211, dated July 12, 1881.

Application filed January 22, 1881.

To all whom ti may concern:

ing at Three Mills Lane, Bromley-by-Bow, in the county of Middlesex, England, have invented certainnew and useful Improvements,

in Fire-Grates, (for which I have received Let.- ters Patent in England, No. 4,972, dated 29th November, 1880;) and I do hereby declare that the following is afull, clear, and exact description of the invention,'which will enable others skilled in the art to whichit appertains to make and use the same.

This invention has for its object improvements in fire-grates of the class provided with fuel reservoirs or chambers, from which fresh fuel may be supplied to the fire as needed.

In order to prevent the formation of smoke, I cause the coal to be heated in a partiallyclosed chamber before it is brought into the open grate to be burned. I provide such a chamber at the back'of the grate in the position which in domestic fire-grates is usually occupied by afire-lump. The chamber is closed at the top and bottom, back and sides, but is open in front into the grate. The fresh coal is placed in this chamber at the back of the fire, and here, where it is not exposed to the upward draft of the fire, it becomes gradually heated. By suitable appliances the fuel can be drawn forward out of the chamber to supply the fire in the grate when this has burned low. Any vapor which may be liberated by the coal while in the chamber passes among the glowing fuel in front lying in the fire-grate, and so is consumed. When the fuel is drawn forward into the fire-grate it, having become thoroughly heated in the chamber, will burn without emitting that cloud of smoke'which is evolved from fresh coal placed on the top of a glowing fire.

In order that my said invention may be most fully understood and readily carried into effect, 1 will proceed to describe the drawings hereunto annexed, preparatory to a specific designation of the subject-matter claimed.

Figure 1 is a vertical section from front to back of an open fire-grate constructed in accordance with my invention and adapted for domestic use. Fig.2 is a sectional plan of the (No model.) Patented in England November 29, 1880.

same, the section being taken on'the line 1 1 in Fig.1.

0a are the front bars, and b b are the bottom bars, of the grate, both much in'the usual position.

0 c are the side cheeks, and d is a door, by which the chimney can be closed when the fire-place is out of use. All these are ordinary and well-known parts.

e is the fuel-reservoir or supply-chamber at the back of the grate. It is a horizontal extension or box, forming a backward continuation of the space in which the fire is contained, the front of the boxor chamber being open for its full height and width, or terminating without obstruction in'the fire-space or grate proper. The bottom of this box is a dead-plate, which extends so far to the front that the bottom grating, b b, is rendered thereby somewhat narrower than usual from frontto back. Within the open front chamber, 0, there is a movable back plate, f, which is of a height and width about corresponding with the internal height and width of the chamber, and is capable of being moved within the chamber from back to front, and vice versa, by means of the bent bars g g, which are attached to it, and serve as handles by which to reciprocate it from the front of the grate. These adjustingbars 9 9 pass through holes in the back of the chamber 0, and also through other holes in the curved plate h underneath the bottom bars of the fire-place. The bars gg are thus controlled or guided in their movements, and when they are drawn forward they bring with them the pusher or back plate, f, and fuel in the chamber e in front of this plate is pushed out into the open fire-place. When the plate f is caused to return to the back of the chamber e the chamber will be empty, or nearly so, and it should be at once filled with fresh coal.

There will be sufficient space over the top of the fire in the grate to permit of coal being filled into the chamber 0 without difficulty. The curved plate It below the fire-bars also serves to direct the draft approaching the fire and cause it to pass briskly upward between the bottom bars, I) b, so that the front of the fire may be kept bright.

k is a curved plate, hinged at the front of the door d, and which, when the fire is well alight, is moved forward into the position in which it is represented in Fig. 1, and aids in keeping the draft to the front of the fire, so that very little air finds its way among the fuel at the back of the grate or into the chamber 0. Consequently the fuel in this chamber emits little or no smoke, but it becomes heated and prepared to be burned in the fire-grate, and such gases as it evolves pass, in great part, amongtheignited fuel and are consumed. The access of air to the fuel in the chamber 6 may be further checked by attaching a narrow flap to the curved plate 70 near the hinge. This heel-extension or flap 70, when the plate It is back against the door 01, will stand in a horizontal position, or nearly so, as shown by dotted lines in Fig.1. When the curved plate It is moved forward to the position in which the drawings show it, the flap will incline downward and check the entrance of air into the upper part of the chamber.

9 is a plate or bar, which is fixed to the bars g g at front. This bar 9, as represented in section in Fig. 1, is provided with a series of holes, which are represented by dotted lines in Fig. 2. The purpose of the perforated bar 9 is to facilitate the drawing forward of the fuel when it is to be pushed out of the chamber 0 into the open fire-place. The end of a poker is inserted successively in the holes and pushed or worked as a lever against the front bars, a, of the grate, and the bars 9 g and plate f are thus prized forward.

My improvements are applicable to kitcheners and ranges.

I claim as of my own invention- 1. The combination, substantially as hereinbefore set forth, of the open grate, provided with the rearwardly-extended open-front box orfuel-supplying chamber, and the movable plate or reciprocating pusher fitted in said chamber, wherebythe fuel in the chamber may be pushed into the grate and the chamber be again supplied with fuel passed in from the front of the grate over the fire, as described.

2. The combination of the grate having the open-front fuel-supplying chamber extended rearwardly therefrom, the movable plate or pusher fitted in said chamber, and the adjusting-bars connected to the pusher and extend- I ing to the front of the grate, substantially as and for the purpose hereinbefore set forth.

3. The combination, substantially as hereinbefore set forth, of the grate, the horizontal extension or fuel-supplying chamber at the back of the grate, the draft-directing plate h, and the adjustable plate k, for the purpose described.

4.. The combination of the grate, the fuelsupplying chamber at the back thereof, the
